Claims.

This invention relates to Venetian blinds and more particularly to a bracket attachment therefor.

It is the principal object of this invention to 5 provide a bracket for each end of the Venetian blind which is so formed as to hold by a spring clamping action both the head rail and the valance of the Venetian blind in fixed relation to said brackets without the use of nails, screws or bolts; which brackets are further so constructed as to permit the attachment thereof to a window frame either on the outside thereof or on the inside of the windowjambs, and which brackets function to form with the attached valance and head rail an enclosed separable head bracket taking the place of the conventional enclosed fixed head blind thus permitting by virtue of its construction instant access to all moving parts by simply pulling or lifting off the front or valance.

Another object of the invention relates to'forming the end brackets from sheet metal stampings, each bracket being formed of two separate sheet metal stampings attached together one receiving the head rail and the other the valance, the former being supported by the latter and the latter being so formed as to'provide integral spring fingers for applying the spring clamping pressure to hold the head rail and valance in position; said bracket being of neat appearance, simple in construction, cheap to manufacture and efiicient and satisfactory in use.

With the foregoing and other objects in view, the inventionresides in the novel arrangement and combination of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

A practical embodiment of the invention is illustrated in the accompanying drawing, wherein:

Figure 1 shows in elevation the head bracket 1 of a Venetian blind mounted in the upper part of a window frame.

Figure 2 is a cross sectional view thereof taken on line 2 2, Figurel.

erence:-

Figure 3 is a perspective view of the right hand The Venetianblind enclosed head bracket construction constituting this invention is an improvement over that shown in the application of Jean N. Kirch, Serial Number 178,229, filed December 6th, 1937, is indicated generally in Figure 1 by the reference character I 0, and is shown mounted between the jambs l I of a window frame" l2, said head bracket supporting a Venetian blind (not shown) and housing the operating and tilting mechanism (also not shown) for said Ve- 1o netian blind, all in the manner well known.

Y At each end there is provided end supporting brackets l3and l4 that attach to the window frame I2 and which further support the head rail and valance of the Venetian blind in the manner 5 to be hereinafter described. The brackets l3 and I4 may be respectively designated as a left end bracket and a right end bracket viewing Figure 1.

As both end brackets l3 and I 4 are structurally identical, one being but the reverse of the other, 20 a detailed description of only the right end bracket M will be given. I

In Figure 3 the right end bracket I4 is shown in perspective and in the main is formed as a stamping from a single sheet of relatively heavy sheet 25 metal to provide a substantially rectangular fiat side wall I 6 which at its upper edge and at its rear edge is formed with bent over portions normal to the plane of said side wall I 6 to define, respectively, a top wall I! and a back wall I8; 30 both of said walls being of equal width and extending for the full length of the adjacent edges of said side wall, with the opposed end edges of said top and back walls in abutting engagement to define a right angle corner 20. At the corner 2l of the side wall I 6 diagonally opposite the corner 20 there is provided a seat 22 constituting an integral part of said side wall normally extending from the lower edge 23 thereof and bent over, as clearly shown. The seat 22 lies horizon- 40 tal and is parallel to thetop' wall I1, and is provided with an upstanding vertical lug 24 at its rearend and at its front end with an upstanding slightly outwardly inclined lug 25 that lies wholly outwardly beyond the front edge 26 of the 4:, side wall ii, for a purpose to be hereinafter described. v

Positioned below the top wall I! and between the front and rear edges of the side wall I6 is a shelf 28 formed of sheet metal and having a 50 depending attaching flange 29 and at its rear transverse edge an upstandingabutment 3D. In order to properly position the shelfv on the side wall [6 said side wall is provided with a tubular boss 3| which is adapted to fit within an opening 32 in the flange 29, which opening is countersunk to allow the edge of the boss to be flared or peened out as at 33 in the manner of a tubuiar rivet to securely fasten this portion of the flange in place. boss 3] and opening 32 are positioned at predetermined points whereby to properly space the shelf 26 from the top wall I1 and back with the shelf 26 fastened at one end as above indicated, the'fiange 29 may be secured at other points as at 34 and 35 by riveting or spot welding, see Figure 2. When so fastened the shelf .25 is parallel to the top wall l1 and the abutment 35 is parallel to the back wall l8. Formed in the shelf 28 are openings 36 to receive fastening elements such as screws, if its is desired to securely attach the bracket to an end of a head rail '40 to be seated on said shelf.

In line with the opening 4! as defined by the tubular boss 3] and adjacent the lower edge 23 of the side wall is another opening 42, both of which are adapted to receive fastening elements for attaching the bracket l4 to a supporting structure such as the lamb l I of the window frame l2. Similar openings 43 are provided in the back wall l6 to receive fastening elements for attaching the bracket M to the face of a window frame or to a wall or any other supporting structure.

To provide the resilient or spring clamping action as contemplated by this invention there is provided on the top wall 11 two forwardly extending spring fingers 45 and 46 formed by slotting said top wall as at ,4"! and 48 from a point substantially midway of the'length of said-top wall to the forward edge thereof. The spring fingers 45 and46 are preferably of the same width, the spring finger '45 being made longer than the spring finger 46. At their free ends the spring fingers 45 and 46 are provided with depending V-shaped terminals 49 and 50, respectively, which serve as looking or holding elements in a manner to be hereinafter described. Preferably the length of the spring finger 45 is such that the locking terminal 49 projects outwardly beyond the front edge 26 of the side wall l6, in

- the manner clearly shown in Figure 3. The locking terminal 56 on the spring finger 46 is disposed substantially :in the vertical plane of the front edge portion of the shelf 26. To provide a proper degree of spring pressure the spring fingers 45 and 46 .are normally bent or depressed downwardly from the plane of the top wall l1. If desired the spring fingers 45 and 46 may be suitably hardened and tempered, however the in-" herent resiliency of the sheet metal out of which the bracket is formed will provide the requisite degree of resiliency necessary in the spring fingers particularly when depressed as above indicated.

As pointed out above, the two. complemental left and right end brackets l3 and I4 constitute a pair of brackets :for supporting and attaching the valance 53 and head rail 40 of a Venetian blind, and are each suitably attached as for example to the lambs H of the window frame I2. The head rail 46 of the type well known carrying the Venetian blind proper as well as the opcrating and tilting mechanism therefor is supported at its ends on the shelf 28 of each bracket,

being placed thereon "with the inside face of the head rail contacting the abutment 36. When so positioned the spring finger 46 will bear on the top face of the head rail 40 to tightly press the same on the shelf 26 to thus hold the same in place. The locking terminal 50 of the spring finger 46 will overhang the upper edge of the bee. rail, see Figure 2, and will prevent outward movement of the head rail 40. Thus it is seen that the head rail is retained on the brackets l3 and I4 without the use of fastening elements such as screws, bolts or'nails.

In a like manner the valance 53 is supported on the seats 22 of the end brackets l3 and I4, lateral movement of the same on said seats being prevented by the lugs 24 and 25. The valance 53 is held in upright position by the spring pressure exerted thereon by the spring finger 45, the locking terminal 49 acting to prevent outward movement of said valance relative to the brackets. By virtue of the inclination of the lug 25, the valance is applied in position by placing the lower edge of the same on the seat 22 of each bracket and pushing the top edge of the valance rearwardly to a vertical position against the action ofthe spring fingers 45 in the manner readily apparent.

It will be appreciated that the form of end brackets as described and shown will permit 7 ready access to the interior of the head bracket by simply pulling the valance 53 oil the brackets i3 and 14. In a like manner the head rail 40 may be removed for repair or replacement. The construction is such that no screws or other fastening elements are required,'each bracket constituting a self-contained unit of great simplicity. As all of the parts of the end brackets are disposed on the inside of the side wall the same on its outer side presents a smooth and neat appearance that harmonizes with any type of window, wall or frame structure as well as with the decorative scheme thereof.
